Summary: | 碩士 === 國立屏東科技大學 === 機械工程系所 === 98 === The purpose of this study is investigate the reverse engineering technique for the reconstruction of the CAD model for field hockey stick. This study first adopts Finite Element Analysis (FEA) and Experimental Modal Analysis (EMA) to perform model verification for field hockey stick. Both FEA and EMA results were compared in order to validate finite element modal. The natural frequencies and mode shapes can be obtained by FEA. Experimental natural frequencies, damping ratios and mode shapes of the field hockey stick can also be obtained by EMA. From the verification between theoretical and practical structural modal testing results. The finite element modal can be treated as an analytical model. Finally, the field hockey stick in two types of boundary conditions, and perform theoretical analysis in order to compare their vibration characteristics and differences, find the relationship between the boundary conditions.
